well, got some injectors, an engine wiring harness, fan harness and pcm in the mail today. Time to get to work after I clean up the nasty ass intake manifold that is all built up with carbon/coked oil.
Question for Allen, if this is supposed to be a 5 wire hookup, what do I do with the other 20 connections? :laugh:
The fan harness came in a nice neat little package that I can customize however I like. :thumb:
BTW, I need spacers and longer bolts for the fuel rails when using the longer new injectors. Too bad its not part of the standard kit. Allen, do you have those, too? I need some badly. Let me know ASAP so I can go one way or another. I can make some if I must but not my favorite way to do it.
Tonight, added the LS1 type injectors to the truck intake. For those wanting to know what's involved I'll go into a little detail. Remember to disconnect your battery before doing any electrical work. The intake was already off this engine so some additional items may need to be removed from your's to get to the fuel rails.
1.) Remove the fuel line connection from the fuel rail and be prepared to catch a lot of fuel out of the rail.
2.) Unbolt the 4 fuel rail retainer bolts.
3.) Disconnect the 8 fuel injector connections from the injectors.
4.) Disconnect the fuel pressure regulator vacuum hose at the intake manifold.
5.) Pull the fuel rail and injectors out of the intake manifold
6.) Use a screwdriver and slide the upper retainer clip off the fuel injector to release the connection of the injector to the rail. Repeat 7 more times.
7.) Pull the injector out of the fuel rail. Mine took a lot of pulling and twisting to get them to release.
8.) Put a little motor oil on the seals of the new injectors. Hopefully your injectors came with seals, if not install new seals(don't reuse the old hardened seals).
9.) Install the injector retainer clip on the new injector. There are two slots, on the truck put the retainer on the lower slot that doesn't go all the way around the injector.
10.) Install the injector in the fuel rail until you feel it lock into place. Repeat 7 more times with the rest of the injectors.
11.) Re-install the fuel rail assembly. You will notice that the fuel rail now sits quite a bit higher. To fix this you need to get some 6mm x 1.0 bolts to replace the factory ones, 40mm long is the length I bought. You will also need some shims to go between the intake and the fuel rail. I bought brass fittings at the Home Depot that were about 13/16" long and then ground them down to 11/16" tall. They already had a hole in them so the new bolt went through without any problems. Be sure to put a washer between the head of the new bolt and the fuel rail mount. Don't overtighten the bolts, the rails are delicate.
12.) Clip the fuel lines back onto the fuel rail.
13.) Reconnect the vacuum hose from the fuel pressure regulator to the intake manifold.
14.) If you didn't have Fbody electrical connectors on you injectors, you're going to have to buy adapters or solder new ones to the stock wiring harness. If you add new ones, don't just twist and tape them, solder and shrink wrap them or you'll end up with problems down the road due to corrosion.
15.) Adjust the tune in the PCM for the new injector flow rate.
16.) Turn key and go have some fun! Remember we all love burnout videos and drag racing videos from the track. :thumb:
lol....1 wheel peel....
man sounds like everything is coming together nicely...
how many lbs are the ls1 style injectors greg?
Actually, all 8 of them maybe weigh 1 lb total. :lol:
60 lb injectors, I do believe.
